Hi Philippe
Best wishes for a speedy recovery.
I can't recall if the reference is correct but I think it was in Squadron Signal Walk Around no. 42 that a reference was made to the manufacture of the rudders with a broad chord trim tab at Obertraubling.
Don't think I can attach the photo from the book here. If either of you want a copy of the page PM me and I'll send one off to you.
The book was available for viewing on a site called Librarum but the site has since disappeared.
I did notice that some of the rudders were of a dark color at Obertraubling as well. Maybe already primed and painted?
Again all the best.

Vince...
